Embark on an epic saga in Vaianaut, a gripping historical fiction novel that weaves a tale of survival and friendship. Lily, a woman rendered immortal under enigmatic circumstances during the Cretaceous Era, awakens in the Ice Age, amid a world reshaped by the catastrophic asteroid that doomed the dinosaurs.

Unchanged by time’s relentless march, Lily encounters early humans, forges a poignant friendship with another time-traveler, and experiences the raw beauty and brutality of Earth’s evolution. As she moves through history, Lily’s eternal life is marked by the joys and sorrows of existence: from the colonization of continents to the ravages of war, and the eventual return to a life that seems all too familiar yet forever changed.

As the Earth evolves and faces the brink of desolation, Lily finds solace in the companionship of another immortal. Their bond becomes a beacon of hope in an increasingly desolate world, and together they face the ultimate test of time.

Vaianaut is a story of unending life amid the transient moments of history, a profound exploration of what it means to be truly immortal. It is an exploration of what it means to live forever, to love beyond time, and a haunting reflection on the solitude immortality can bring.

This novel will captivate readers with its rich tapestry of history, adventure, and the timeless quest for meaning in an ever-changing universe.

Give me a minute. Ok. This was without a doubt the best book I’ve read in a long while! Author V. Casa wrote a very good first book in this series in Vaieon and I liked it very much!

Believe me though, Vianaut is so much better! I was sucked in early and Lily’s travels, loves, and losses never let me go until the last word.

Casa spins an emotional yarn that sucks you into the story and she does it seemingly with little effort. The scope of Vianaut is massive and is difficult to encompass, in a wonderful way, and I felt like I had to become immortal myself to endure alongside the very strong FMC, Lily.

Casa’s vision is amazing and original and I’m very happy she allowed me to ARC read this wonderful book. I imagine I’ll have a physical copy on my shelf when it becomes available.

Thank you V.

- - No spoilers for Vaieon - -

Lily’s story is one that oscillates between triumph and devastation. The reader is brought alongside this journey and the carefully crafted imagery provides an immersive experience for the reader. I have never read a book quite like Vaieon or Vaianaut before, and I am so glad that I was able to discover this unique experience. If you are unsure if you should try this series, then I would ask: do you want to be transported into an exciting new time period? Do you want to experience heartbreak and joy alongside a deeply relatable main character? Do you want to see a story of resilience, hope, and unexpected relationships? If you answered yes to any of those, then I think this series is right for you, and I hope you give it a chance.

- - Spoilers for Vaieon - -

If you thought Vaieon was an emotional book then you are in for a doozy with Vaianaut. As Lily grapples with her immortality she has to overcome the devastation of loving people who are doomed to leave her. She both wishes for time to move more slowly so she can cherish her relationships and for time to move quickly so she can return to her original timeline. And through it all, the reader is brought along through Lily’s emotional turmoil. One of the best aspects of this book is the pacing. When Lily settles down to live her life, the pace feels slow and deeply immersive, but when something causes Lily to hide away or shut down the pace quickly moves through decades leaves the reader feeling just as disoriented as Lily herself feels. All of the best aspects of book 1 — Lily’s steadfast resilience, the excitement of exploring new time periods, and the heart wrenching themes of grief and loss — are expanded upon in this book and the reader is able to connect so much more deeply with Lily as she interacts with new characters and new environments. I am so amazed by the story V. Casa was able to create with this book, and I wholeheartedly recommend it to anyone who loved the first one!


I am truly so honored to have had the opportunity to be an ARC reader for this book, and I am so excited to support V. Casa in all of her future ventures, because she clearly has a talent for storytelling and I can’t wait to see where her stories go next.

*Spoiler free

I was lucky enough to be a beta reader for the second installment of V. Casa's Vai trilogy, Vaianaut.
I am glad, because with the way the first book ends, I was eager to get my hands on the sequel!

With this second installment, a lot happens. We delve even deeper into Lily's journey. I enjoyed the fact that book two has more dialogues than the first (and we know why that is but still). To me, it made it easier to be even more immersed in the story. Some parts of the story were very emotional, pulling at my heartstrings. Very well done.

I find that the author's style has immensely matured. A lot of work was put into the book and it shows, from the plot to the writing style.

V. Casa seems to be a fan of cliffhangers; I expect a tome three, I need to know more!

Sequel to Vaieon, Vaianaut catapults us into a brand-new era: the Ice Age. We leave behind the Cretaceous period and the aftermath of the asteroid that ended the dinosaurs, as Lily is thrust forward in time to a world on the mend; a world frozen, hostile, and utterly transformed.

Lily wakes up in this stark new environment stronger and wiser than when we last saw her. She’s hardened now…mentally, physically, emotionally. She carries the weight of knowledge, the scars of survival, and the curse of immortality. While she cannot die, everything around her certainly can. And many things still try to end her.

The Ice Age brings a different kind of danger: bitter cold, hungry beasts, and an Earth still raw from its wounds. But Lily isn’t entirely alone anymore. She’s found kinship—l (if only temporarily) with some of the earliest Homo sapiens. This development is both a gift and a tragedy, as she already knows their fate.

When she eventually makes it “home”, things aren’t roses and sunshine. Returning to a time where there are identification markers, people that know you, and a family who is none the wiser proves challenging and bittersweet. How do you form new bonds or nourish existing ones when you’re destined to outlive every face, every friend, and every story?

As with Vaieon, Vaianaut takes readers on an emotional rollercoaster. There are thrilling highs fueled by Lily’s resilience and grit, and devastating lows that remind us of the price of living forever. This sequel expands the world with more characters both human and animal and brings in new dynamics, dialogue, and heart. The addition of companions makes this chapter richer and more layered, and we finally start to get some long-awaited answers. It’s satisfying and grounding, even when those answers hurt.

If I had one critique, it would be Lily’s internal monologue. At times, it veers into repetitive or overly introspective territory. Then again, considering her isolation and trauma, it makes sense. She’s had no one to talk to but herself for… ages. I can’t entirely place why, but I had different feelings for Lily this time around. I love that she’s fiercer, wiser, and braver but her coldness is sometimes jarring. Again, I understand why that is the case but it took more work for me to sympathize with her.

V. Casa has crafted something truly special here. I’m invested, I’m emotional, and I’m absolutely crossing my fingers and toes for a third installment. Let’s see where time (and Lily) take us next.

Big thanks to the author for the e-copy in exchange for an honest review!

So, I read V. Casa’s first book, Vaieon, and loved it. I honestly don’t think I could love her other books more. I was wrong. Vaianaut just raised the bar so much higher.

In Vaianaut, we continue our journey with Lily through time as she creeps closer to the year her family still is.

This one starts in the middle of an ice age, and throws Lily into a new and foreign land, but one she is ecstatic to explore. And she finally find out she is not the only time traveler. It add a whole new depth and layer to Lily’s story, and makes her immortality more bearable.

As the author leads us on a walk through the ages, she brings us into rich and vibrant worlds of the past, and Lily’s ability to savor every moment-adapting as the need arises. Unfortunately, it isn’t all happiness and contentment. Lily is faced with immense heartbreak as she grows closer to people she starts meeting along her journey. The past brings with it cruelty, greed, and violence, and Lily has to endure all of it. And despite finally finding her family, and getting to spend time with the once more, the reality of her inability to die brings a sadness that lingers for a long time.

We not only get a glimpse of the last, but also the future, and how it can change in the blink of an eye. But Lily is not alone in her continual journey through the ages. She meet someone who is just like her, and they tackle whatever comes their way however they can-even if that means possible living long enough to see our world come to an end. Does it? I guess you’ll have to read and find out.

This novel is beautifully written, and causes our imagination s to bloom with possibility. It was so easy to imagine myself walking right next to Lily and feeling all the ups and downs she lived through. I loved the characters she brought into Lily’s path, and even gives her a chance to love again in a comforting, life giving way. I cannot recommend this book highly enough, and I can’t wait to see where Lily’s story goes. All the stars in the world.

A huge thank you to the author for my arc. Much opinion is my own.

It’s 1:46am, I ate this book up!

I really enjoyed book 1, but book 2 is even better. As you follow Lily’s journey through time you really explore what it is to be human. Is she even that anymore? Who is she? What is she? Does it even matter?

“It felt like her heart had been scattered throughout history, and she no longer knew where she truly belonged. With her family in the future? With her pack in the past? One version of herself had slipped through her fingers like water, while the other had been out of reach for so long that she could hardly imagine how she would fit in this life after all this time.”

Ugh the heartache and devastation she experiences in this book are so gut wrenching, but nothing tops the feeling of her crushing sense of loneliness. :(

3 Favorite Characters:
Ohserase - Allowed her to feel love for a child only like a mother can.
Meera - Allowed her to feel friendship and hope for the future.
Kwan - you have to read about that yourself.

If you are a lover of anthropology and science fiction, this is the book for you, but be prepared…it ends on a massive cliffhanger. I look forward to book 3!

V so kindly sent me an eARC. After reading Vaieon, I couldn’t wait another second to read Vaianaut.
The start of the second book goes 0-humanity quickly. V takes the reader on a hauntingly beautiful journey with Lily through humanity’s history. I was not prepared for the emotions I would experience; but that is just a testament to the way V wrote her characters and the plot.

If you enjoy time travel and the idea of what it would really be like to be immortal on Earth, you’ll love this book. Vaianaut continues Lily’s journey. It’s a beautiful mix of survival, reflection, and connections, especially with another immortal. Can’t wait for the final book in the trilogy!

This is the 2nd book in the series and we get a bit more of an explanation (or a theory) around what happened. Questions answered, more arise. Refreshing to see Lily’s interaction with others and a lot more dialogue.

Time passes and Lily continues her mountain top epiphanies. And she was right “surviving wasn’t always the kindest option”.

The story joins our current timeline (sort of) and there was so much history to cover. Missed what I would have covered but hit some interesting, and depressing, points in history. Reconciling with her family was sweet, and sad, but well told. Love re-found, lost, then found.

I didn’t like the ending so much. Did peak my interest for what comes next. A deep, and dark, dive into sci fi.

If I thought Vaieon was incredible, Vaianaut took the story to a whole new level. The world expands dramatically as Lily wakes up in a post-apocalyptic ice age, and the stakes somehow get even higher.

The atmosphere is stunning — icy landscapes, massive creatures, and a sense of isolation that feels bone-deep. Yet Lily’s determination and growth make the book feel hopeful and powerful. V. Casa’s attention to detail is unmatched; the survival elements are realistic and immersive, and the emotional depth is what makes this story truly unforgettable.

This sequel proves that the Vai Trilogy is something special. It’s heart-pounding, emotional, and gorgeously written.

Another five-star read from me — and now I’m counting down the days for Book 3!

Book Review: “Vaianaut” by V. Casa

I have been given the absolute honour of being a beta reader for this, so early on that there isn’t even a cover for the book yet!!!!

From the start, Casa expertly picks up the threads left dangling from the first book, delivering an exhilarating continuation that maintains its predecessor’s momentum. The immediate mention of “baby boy” strikes a nostalgic chord, reinforcing the emotional stakes for fans who have grown attached to the character from the first book.

Lily’s character arc is a central highlight, showcasing her evolved confidence in hunting and self-defense compared to the previous book. The growth within her is so empowering to read about. Yet the struggles she faces in this second book are…grande to say the least.

Lily’s profound sense of displacement—caught between her family in the future and her pack in the past—captures the essence of her internal conflict, effectively drawing readers into her tumultuous journey.

The portrayal of Lily’s experiences, from sitting naked among the burnt remains of humans to the heart-wrenching sight of 23 dead children, is both haunting and powerful. These moments emphasize the depth of her struggle and the stark brutality of her reality. The eruption and the grim events that follow underscore the high stakes of her quest.

Casa brings the narrative full circle in a poignant manner, as Lily returns to her past patters in life, living in a hut she built by a water source despite it being multiple lifetimes later. This return, juxtaposed with her deep connection to Kwan—particularly their final moments together as the asteroid looms—evokes a strong emotional response. The shocking twist of eternal immortality in a massive cliffhanger delivers a breathtaking cliffhanger that will leave readers eagerly anticipating the next installment.

Overall, “Vaianaut” is a powerful continuation that combines emotional depth with high-stakes action, making it a must-read for fans of the series. Casa’s ability to weave together intense personal and cosmic elements ensures that readers are not only entertained but also profoundly moved.

Forever grateful to the author for allowing me to be a beta reader. I absolutely LOVED Vaieon so I jumped on the opportunity and I was not disappointed at all.

After living her life in the Cretaceous Era, Lily didn’t know what would happen when the meteors would hit the earth and make it unlivable for centuries. She was immortal, yes. But she still didn’t know what that meant.

In this book, Lily is watching the world change and instead of one single era, you get to take a “look” at a few different eras along with her. Not only is she exploring new surroundings but Lily is FINALLY making contact with other human beings and is able to start building relationships with people again.

She’s also gaining insight into her experience from other people on her journey of finding out why she was chosen to go on this journey, with little Easter eggs on the way.

We’re introduced to tons of amazing characters but my absolute favorite will always be Kwan. He’s such a strong-willed, sweet man and I knew I was going to love him from the beginning of his life on “paper.”

I’ve grown so much love for Lily as a character and her resilience as well as passion to adjust and evolve to the world around her. My heart was so warm when she was able to make connections with living things that could actually speak back to her and carry on conversations.

This is such an absolutely amazing series and I will forever have a place in my heart for these books. 😭😭 I love them. DEFINITELY going on my Christmas wish list (mom I know you follow me, take notes and stay away from my smut reviews)
